King Coil Springs are not repackaged car springs, they are specially designed and manufactured for off-road use and will work perfectly with King's 2.0, 2.5, and 3.0 coil over shocks. Each coil spring is made of the finest quality, high tensile, chrome silicon wire available and powder coated King Shocks blue to protect against corrosion.

Spring rates range from 50 lbs per inch tender springs to 1,000 lbs per inch heavy duty springs for large vehicles. All spring rates are linear and consistent throughout the entire spring length. Up to three different springs can be used on a coil over shock when the appropriate dual or triple rate coil carrier hardware is installed.
